MSI 6900XT - black screen/crash?

[Jordan Harley]

Hi, hoping someone here can help me out as i have literally tried everything to resolve this problem. The card can work for hours on end with no issues then other times it just black screens on my main monitor and freezes my second monitor but can still hear sound of video/games. At first i assumed it was my 750 watt psu so i just went ahead and upgraded it to a 1000 watt psu and still get the same problem. On restart i get an AMD software pop up on the bottom right: Default Radeon wattman settings have been restored due to an unexpected system failure.

Spec:
5800x3d
Liquid Freezer II 280
32gb corsair vengeance 3600mhz
Gigabyte X570 AORUS Elite
Be Quiet Pure 11 1000 Watt psu

Any help would be much appreciated.

Mobo and gpu are on latest driver/bios, i have tried using ddu etc, cables are decent enough quality and yes my gpu is daisy chained.

I will give it a go with the cables. memory was from an existing rig so its not that.

I seem to have fixed the issue, I Disabled MPO like @Mercurial suggested,disabled AMD overlay completely and manually set the cards speeds and fan in msi afterburner and it seems to be working fine now. So thanks for the help guys.
